Findings offer potential mechanistic and clinical insights in the development of cellular therapy Lomecel-B™ for mild Alzheimer’s disease (AD) Lomecel-B™ capacity to inhibit MMP14 correlates with improved clinical and biomarker outcomes in mild AD Immunomodulatory and pro-vascular effects of Lomecel-B™ in mild AD potentially driven by ability to exert MMP14 inhibition which may protect TIE2 receptor integrity in human AD patients MIAMI, Oct. 29, 2024 (GLOBE NEWSWIRE) -- Longeveron Inc. (NASDAQ: LGVN), a clinical stage regenerative medicine biotechnology company developing cellular therapies for life-threatening and chronic aging-related conditions, today announced that its submission entitled “Lomecel-B inhibition of MMP14 activity predicts Lomecel-B bioactivity in the treatment of mild Alzheimer’s disease” was presented as a late breaking poster presentation at the 17th edition of the Clinical Trials on Alzheimer’s Disease Conference (CTAD24) taking place October 29 -November 1, 2024 in Madrid, Spain. “As a medicinal signaling cell therapy that has multiple potential mechanisms of action to address inflammatory responses in the brain, Lomecel-B™ offers the potential to address the underlying pathology of Alzheimer’s disease,” said Joshua Hare, M.D., Co-founder, Chief Science Officer, and Chairman at Longeveron. “This data adds to the positive clinical information from the Phase 2a CLEAR MIND clinical trial that showed Lomecel-B™ improved cognitive function, quality of life, and brain volume in the treatment of mild Alzheimer’s disease. We are very encouraged by the safety profile and efficacy evidence that support the differentiated therapeutic potential of Lomecel-B™ in Alzheimer’s disease.” From the Poster: Matrix metalloprotease (MMP) activity is reportedly upregulated in AD. The researchers hypothesized that excess MMP14 activity may contribute to AD pathogenesis, at least in part, by cleaving TIE2 (Tyrosine kinase with Immunoglobulin and Epidermal growth factor homology domains), a cell-surface tyrosine kinase receptor for the angiopoietins, which activates downstream signaling pathways that regulate endothelial cell health and inflammatory responses. They tested the hypothesis that Lomecel-B™ capacity to inhibit MMP14 correlates with improved clinical and biomarker outcomes in mild AD. The researchers measured MMP14 inhibitory (MMP14i) activity, levels of TIMP2 (tissue inhibitor of metalloprotease 2), and VEGF-A (vascular endothelial growth factor-A) in the lots of Lomecel-B used in the CLEAR MIND trial. Supernatant from Lomecel-B CLEAR MIND lots contained MMP14i activity, high levels of TIMP2 and VEGF-A protein. Patients receiving Lomecel-B lots with higher levels of MMP14i activity demonstrated enhanced responses vs. placebo on the composite Alzheimer’s disease score (CADS, the study secondary endpoint) than those who received low potency lots. Similar associations were evident with responses in the MoCA, ADCS-ADL, and left hippocampal volume. High MMP14i lots were also more effective in suppressing elevations in soluble (degraded) TIE2 in study patients, suggesting a potential role for MMP14i in AD treatment. Poster Conclusion: Together these findings suggest that ability to exert MMP14 inhibition may protect TIE2 receptor integrity and underlie, at least in part, the immunomodulatory and pro-vascular effects of Lomecel-B in mild AD. The findings offer potential mechanistic and clinical insights in the development of cellular-based therapy for AD. The abstract of the poster will also be included in the special CTAD edition of the Journal of Prevention of Alzheimer’s Disease (JPAD), the official journal of the CTAD conference. About Lomecel-B™ Lomecel-B™ is a living cell product made from specialized cells isolated from the bone marrow of young healthy adult donors. These specialized cells, known as medicinal signaling cells (MSCs), are essential to our endogenous biological repair mechanism. MSCs have been shown to perform a number of complex functions in the body, including the formation of new tissue. They also have been shown to respond to sites of injury or disease and secrete bioactive factors that are immunomodulatory and regenerative. We believe that Lomecel-B™ may have multiple potential mechanisms of action that may lead to anti-inflammatory, pro-vascular regenerative responses, and therefore may have broad application for a range of rare and aging related diseases. About Longeveron Inc. Longeveron is a clinical stage biotechnology company developing regenerative medicines to address unmet medical needs. The Company’s lead investigational product is Lomecel-B™, an allogeneic medicinal signaling cell (MSC) therapy product isolated from the bone marrow of young, healthy adult donors. Lomecel-B™ has multiple potential mechanisms of action encompassing pro-vascular, pro-regenerative, anti-inflammatory, and tissue repair and healing effects with broad potential applications across a spectrum of disease areas. Longeveron is currently pursuing three pipeline indications: hypoplastic left heart syndrome (HLHS), Alzheimer’s disease (AD), and Aging-related Frailty. Lomecel-B™ development programs have received five distinct and important U.S. FDA designations: for the HLHS program - Orphan Drug designation, Fast Track designation, and Rare Pediatric Disease designation; and, for the AD program - Regenerative Medicine Advanced Therapy (RMAT) designation and Fast Track designation.
